Do we really care about income inequality?

One reason I don’t take leftist critiques of economic systems seriously is because they won’t make a peep about the ostentatious consumption of Democrat politicians and their families while they rail against income inequality. There are enormous issues to be addressed about the distribution of wealth through productivity and consumption, but business owners at least are spending money voluntarily exchanged for a product or service provided.

Political wealth is being amassed as a function of involuntary taxation, with a substantial proportion of tax revenues skimmed off for the self-aggrandizement of politicians before the remainder finds its way to actual government service and projects, which is generally sub-par compared to private enterprise. Yet Leftists insist that its in the private sphere that oppression is to be found.
